AssetAI Reliability Event Codes
These ISO-compliant, asset-class-based work order identifiers—comprising Symptom, Problem, Failure, Action, and Cause codes—provide the structured database foundation required to track failure frequencies, calculate MTBF, execute predictive maintenance models, and PM intervals.
AssetAI embeds these failure dictionaries directly into your equipment profiles.

What Are Reliability Event Codes?
Aligned with ISO standards, Reliability Event Codes (RECs) provide a structured framework for documenting the entire maintenance lifecycle—from initial operator observations to root cause analysis.
AssetAI embeds this comprehensive, asset-class-based library directly into your equipment profiles.
By automatically mapping these specific code structures to their corresponding equipment classes during data enrichment, the platform streamlines diagnostics, improves trend analysis, and ensures data consistency across the enterprise.
The AssetAI REC Dictionary includes:
Symptom Codes
Capture observable issues reported by operators or work requestors (e.g., noise, vibration, leakage).
Problem Codes
Pinpoint specific equipment issues diagnosed by technicians (e.g., component wear, electrical fault).
Failure Codes
Define the reason equipment fails to perform its function (e.g., bearing seizure, motor failure).
Action Codes
Detail corrective steps taken to resolve issues (e.g., replace component, adjust settings).
Cause Codes
Identify root causes of failures (e.g., inadequate lubrication, contamination).
Eliminating the Development Bottleneck
Manually designing, validating, and configuring a comprehensive failure code for every individual asset class—such as pumps, motors, compressors, and fans—is a massive administrative hurdle. This development cycle typically requires weeks or months of engineering effort, stalling system deployments, and delaying critical benefits such as reduced downtime and proactive maintenance.
AssetAI completely eliminates this development constraint. Because our ISO-compliant reliability dictionaries are embedded directly into the enrichment engine, no manual database configuration or spreadsheet building is required. The platform programmatically attaches the correct code structures to your equipment records during data processing, accelerating system implementation and delivering immediate day-one value.
Real-World Impact
In a typical maintenance environment, a work order closed out with a vague note like “chiller running hot, cleaned out scale buildup from the hard water” completely fragments your data. Important metrics get lost in a free-text narrative that analytics tools cannot read.
AssetAI automatically parses this unstructured history during data enrichment, mapping the complete corrective workflow into precise data signatures under the CHILLER profile:
Symptom: Discharge temperature high
Problem: Tube scale fouling
Failure: Cooling capacity loss
Action: Clean evaporator tubes
Cause: Utility water quality
By codifying the entire workflow rather than just capturing a random failure label, AssetAI builds the comprehensive database foundation needed to calculate precise MTBF, track asset health trends, and optimize your preventive maintenance intervals.
